Summary: | PROBLEM TO BE SOLVED: To provide a multilayer coating film forming method where especially silver metallic coating containing a luster pigment such as an aluminum pigment and the like has many coating colors, various designs and high popularity in coatings for automobiles required for high designing property and the flip-flop property as the index of the designing property of a metallic base coat coating film containing the luster pigment and a multilayer coating film containing a clear coat coating film.SOLUTION: In a multilayer coating film forming method, an aqueous metallic coat containing a luster pigment is coated at a coating object temperature lower than a specific temperature by, for example, less than 25°C, preferably 20°C or less and more preferably 15°C or less when forming a multilayer coating film containing a metallic base coat coating film containing a luster pigment and a clear coat coating film, and a solvent-based clear coat is preferably coated on an aqueous metallic base coat after being coated.SELECTED DRAWING: None
【課題】自動車用塗料において、高い意匠性が求められるようになり、その中でもアルミニウム顔料などの光輝性顔料を含有するシルバーメタリックは塗色が多く、意匠が多彩であることから人気が高い。この意匠性の指標としてフリップフロップ性がある。光輝性顔料を含有するメタリックベースコート塗膜、及びクリアコート塗膜を含む複層塗膜の、フリップフロップ性が高くなる複層塗膜形成方法を提供すること。【解決手段】光輝性顔料を含有するメタリックベースコート塗膜とクリアコート塗膜とを含む複層塗膜形成の際、被塗物の温度を特定の温度より、例えば25℃未満、好ましくは20℃以下、より好ましくは15℃以下に下げて光輝性顔料を含有する水性メタリックコートを塗装する複層塗膜形成方法。好ましくは、水性メタリックベースコートを塗装した後、上に溶剤系クリアコートを塗装する、複層塗膜形成方法。【選択図】なし |
